Amusing, yet sometimes frustrating.
The dialog made me grin in parts, and the added mobility that rage gave Kilzek was an interesting mechanic, but I became repeatedly frustrated by the platform-jumping aspect, due to the fact that I'd always appear to fall off a platform before I reached the actual visual edge of said platform. To put it another way, Kilzek seems to start falling when only half his body is actually tipping over the edge of a cliff, causing the other half of his body to "fall through stone", as it were.
